如何通过一些api获取Windows 7中的电池状态？(How to get battery status in windows 7 via some api?)

我想知道有没有办法通过c＃代码知道笔记本电脑的电池是否已充满电，或者电池已满时是否有任何事件被提起。

i want to know is there any way to know by c# code that laptop's battery is fully charged or is there any event raised when the battery is full.

我猜你可以使用WMI类Win32_Battery 。

有多个字段可能有用 - DesignCapacity ， BatteryStatus ， FullChargeCapacity或ExpectedLife

所以我的猜测是你可以使用WMI读取这两个值，然后计算FullChargeCapacity/BatteryStatus/DesignCapacity/ExpectedLife来查找电池健康百分比数字。

I'm guessing you could use the WMI class Win32_Battery.

There are multiple fields that could be useful - DesignCapacity, BatteryStatus, FullChargeCapacity or ExpectedLife

So my guess is that you can use WMI to read these two values, and then calculate FullChargeCapacity/BatteryStatus/DesignCapacity/ExpectedLife to find the battery health percentage number.
